Fulltext The effect of "group detailing" on drug prescribing in primary care

Mastura I, Teng CL

Med J Malaysia, 2008 Oct;63(4):315-8.
PMID: 19385492

The quality of physician prescribing is suboptimal. Patients are at risk of potentially adverse reaction because of inappropriate or writing error in the drug prescriptions. We assess the effect of "group academic detailing" to reduce writing drug name using brand name and short form in the drug prescriptions in a controlled study at two primary health care clinics in Negeri Sembilan. Five medical officers in Ampangan Health Clinic received an educational intervention consisting of group academic detailing from the resident Family Medicine Specialist, as well as a drug summary list using generic names. The academic detailing focused on appropriate prescribing habit and emphasized on using the full generic drug name when writing the drug prescription. Analyses were based on 3371 prescriptions that were taken from two clinics. The other health clinic was for comparison. The prescribing rates were assessed by reviewing the prescriptions (two months each for pre- and post-intervention phase). Statistically significant reduction in writing prescription using brand name and using short form were observed after the educational intervention. Writing prescription using brand name for pre- and postintervention phase were 33.9% and 19.0% (postintervention vs pre-intervention RR 0.56, 95% CI 0.48 to 0.66) in the intervention clinic. Prescription writing using any short form for pre- and post-intervention phase were 49.2% and 29.2% (post-intervention vs pre-intervention RR 0.59, 95% CI 0.53 to 0.67). This low cost educational intervention focusing on prescribing habit produced an important reduction in writing prescription using brand name and short form. Group detailing appears to be feasible in the public health care system in Malaysia and possibly can be used for other prescribing issues in primary care.

Drug use and dosing in chronic kidney disease

Hassan Y, Al-Ramahi R, Abd Aziz N, Ghazali R

Ann Acad Med Singap, 2009 Dec;38(12):1095-103.
PMID: 20052447

One of the most important drug-related problems in patients with chronic kidney disease (CKD) is medication dosing errors. Many medications and their metabolites are eliminated through the kidney. Thus, adequate renal function is important to avoid toxicity. Patients with renal impairment often have alterations in their pharmacokinetic and pharmacodynamic parameters. The clearance of drugs eliminated primarily by renal filtration is decreased by renal disease. Therefore, special consideration should be taken when these drugs are prescribed to patients with impaired renal function. Despite the importance of dosage adjustment in patients with CKD, such adjustments are sometimes ignored. Physicians and pharmacists can work together to accomplish safe drug prescribing. This task can be complex and require a stepwise approach to ensure effectiveness, minimise further damage and prevent drug nephrotoxicity.

Fulltext Perception towards asthma clinical practice guidelines and appropriateness of prescribing practices--a comparison between government and private doctors

Loh LC, Wong PS

Med J Malaysia, 2007 Aug;62(3):210-3.
PMID: 18246909

A self-answered, anonymously completed, nationwide questionnaire survey was conducted between June 2002 and May 2003 among Malaysian doctors through post and at medical meetings. Findings based on 116 government and 110 private doctors who satisfactorily completed the forms (effective respondent rate: 30.1%) showed that more than 70% of government and private doctors claimed familiarity with asthma CPGs but proportionately more private doctors considered them "unworkable" and were reluctant to adopt them in their practice setting, quoting cost as the primary reason. Between those who frequently adopted the CPGs and those who did not, there was an equally high proportion of inappropriate prescribing. Despite the shortcomings of such a survey, our findings suggest that medicinal cost and practitioner's prescribing practices are important in the acceptance and execution of asthma CPGs recommendations.

Physicians' knowledge, perceptions and behaviour towards antibiotic prescribing: a systematic review of the literature

Md Rezal RS, Hassali MA, Alrasheedy AA, Saleem F, Md Yusof FA, Godman B

Expert Rev Anti Infect Ther, 2015 May;13(5):665-80.
PMID: 25813839 DOI: 10.1586/14787210.2015.1025057

BACKGROUND: Knowledge, perceptions and prescribing behaviour are key to antibiotic prescribing. The aim of this paper is to systematically review this.
METHOD: An extensive literature search from 1990 to 2014.
RESULTS: Nineteen articles were included; eight in ambulatory care, seven in hospital settings and four in both, across all countries. Physicians still have inadequate knowledge and misconceptions about antibiotic prescribing. Moreover, some physicians, although aware that antibiotics are of limited benefit in some conditions, still prescribed them. Several factors influenced prescribing, including patients' expectations, severity and duration of infections, uncertainty over diagnosis, potentially losing patients and influence of pharmaceutical companies. Pocket-sized guidelines seen as an important source of information for physicians.
CONCLUSION: Inadequate knowledge of prescribing is prevalent among physicians. However, many physicians were interested in improving their antibiotic prescribing. Multifaceted interventions targeting all key stakeholders, including patients, are needed to improve future antibiotic prescribing.
KEYWORDS: antibiotics; irrational use of medicines; patients; physicians; prescribing behaviour; resistance; systematic reviews

Factors associated with prescribing restriction on oncology formulary drugs in Malaysia

Fatokun O, Olawepo MN

Int J Clin Pharm, 2016 Oct;38(5):1075-9.
PMID: 27586371 DOI: 10.1007/s11096-016-0372-8

Background Drugs listed on formularies are often subjected to a variety of utilization restriction measures. However, the degree of restriction is influenced by multiple factors, including the characteristics and attributes of the listed drugs. Objective To identify the factors that are associated with the levels of prescribing restriction on oncology formulary drugs in Malaysia. Setting Oncology formulary in Malaysia. Method The Malaysia Drug Code assigned to each of the drug products on the Malaysia Ministry of Health (MOH) drug formulary was used to identify oncology drugs belonging to WHO ATC class L (antineoplastic and immunomodulating agents). Main outcome measures Categories of prescribing restrictions, therapeutic class, drug type, administration mode, number of sources and the post-approval use period. Results Oncology drugs having a shorter post-approval use period (p drugs (p = 0.01) and oncology drugs belonging to immunosuppressant therapeutic class (p = 0.03) were all significantly associated with a greater likelihood of being subjected to a higher level of prescribing restriction. Conclusion This study suggests that safety concerns, costs and potentials for inappropriate use were the important considerations influencing a higher level of prescribing restriction placement on oncology drugs in the Malaysia MOH drug formulary.

The methodological quality of guidelines for hospital-acquired pneumonia and ventilator-associated pneumonia: A systematic review

Ambaras Khan R, Aziz Z

J Clin Pharm Ther, 2018 Aug;43(4):450-459.
PMID: 29722052 DOI: 10.1111/jcpt.12696

WHAT IS KNOWN AND OBJECTIVES: Clinical practice guidelines serve as a framework for physicians to make decisions and to support best practice for optimizing patient care. However, if the guidelines do not address all the important components of optimal care sufficiently, the quality and validity of the guidelines can be reduced. The objectives of this study were to systematically review current guidelines for hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP), evaluate their methodological quality and highlight the similarities and differences in their recommendations for empirical antibiotic and antibiotic de-escalation strategies.
METHODS: This review is reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Electronic databases including MEDLINE, CINAHL, PubMed and EMBASE were searched up to September 2017 for relevant guidelines. Other databases such as NICE, Scottish Intercollegiate Guidelines Network (SIGN) and the websites of professional societies were also searched for relevant guidelines. The quality and reporting of included guidelines were assessed using the Appraisal of Guidelines for Research and Evaluation II (AGREE-II) instrument.
RESULTS AND DISCUSSION: Six guidelines were eligible for inclusion in our review. Among 6 domains of AGREE-II, "clarity of presentation" scored the highest (80.6%), whereas "applicability" scored the lowest (11.8%). All the guidelines supported the antibiotic de-escalation strategy, whereas the majority of the guidelines (5 of 6) recommended that empirical antibiotic therapy should be implemented in accordance with local microbiological data. All the guidelines suggested that for early-onset HAP/VAP, therapy should start with a narrow spectrum empirical antibiotic such as penicillin or cephalosporins, whereas for late-onset HAP/VAP, the guidelines recommended the use of a broader spectrum empirical antibiotic such as the penicillin extended spectrum carbapenems and glycopeptides.
WHAT IS NEW AND CONCLUSIONS: Expert guidelines promote the judicious use of antibiotics and prevent antibiotic overuse. The quality and validity of available HAP/VAP guidelines would be enhanced by improving their adherence to accepted best practice for the management of HAP and VAP.

Fulltext The impact of a prescription review and prescriber feedback system on prescribing practices in primary care clinics: a cluster randomised trial

Lim WY, Hss AS, Ng LM, John Jasudass SR, Sararaks S, Vengadasalam P, et al.

BMC Fam Pract, 2018 07 19;19(1):120.
PMID: 30025534 DOI: 10.1186/s12875-018-0808-4

BACKGROUND: To evaluate the effectiveness of a structured prescription review and prescriber feedback program in reducing prescribing errors in government primary care clinics within an administrative region in Malaysia.

METHODS: This was a three group, pragmatic, cluster randomised trial. In phase 1, we randomised 51 clinics to a full intervention group (prescription review and league tables plus authorised feedback letter), a partial intervention group (prescription review and league tables), and a control group (prescription review only). Prescribers in these clinics were the target of our intervention. Prescription reviews were performed by pharmacists; 20 handwritten prescriptions per prescriber were consecutively screened on a random day each month, and errors identified were recorded in a standardised data collection form. Prescribing performance feedback was conducted at the completion of each prescription review cycle. League tables benchmark prescribing errors across clinics and individual prescribers, while the authorised feedback letter detailed prescribing performance based on a rating scale. In phase 2, all clinics received the full intervention. Pharmacists were trained on data collection, and all data were audited by researchers as an implementation fidelity strategy. The primary outcome, percentage of prescriptions with at least one error, was displayed in p-charts to enable group comparison.

RESULTS: A total of 32,200 prescriptions were reviewed. In the full intervention group, error reduction occurred gradually and was sustained throughout the 8-month study period. The process mean error rate of 40.7% (95% CI 27.4, 29.5%) in phase 1 reduced to 28.4% (95% CI 27.4, 29.5%) in phase 2. In the partial intervention group, error reduction was not well sustained and showed a seasonal pattern with larger process variability. The phase 1 error rate averaging 57.9% (95% CI 56.5, 59.3%) reduced to 44.8% (95% CI 43.3, 46.4%) in phase 2. There was no evidence of improvement in the control group, with phase 1 and phase 2 error rates averaging 41.1% (95% CI 39.6, 42.6%) and 39.3% (95% CI 37.8, 40.9%) respectively.

CONCLUSIONS: The rate of prescribing errors in primary care settings is high, and routine prescriber feedback comprising league tables and a feedback letter can effectively reduce prescribing errors.

Lee JL

Int J Clin Pharm, 2020 Apr;42(2):604-609.
PMID: 32095976 DOI: 10.1007/s11096-020-00996-4

Background Prescribing errors in children are common due to individualization of dosage regimen. It potentially has a great impact especially in this vulnerable population. Objective To determine the prevalence and common types of prescribing errors in a Malaysian pediatric outpatient department and to determine the factors contributing to prescribing errors. Setting Pediatric Outpatient Department and Outpatient Pharmacy at a tertiary care hospital in Malaysia. Method This is a prospective, cross sectional observational study where all new prescriptions received by the outpatient pharmacy from patients attending pediatric out-patient clinic were included for analysis. Descriptive statistics and logistic regression were used to analyze the data. Main outcome measure Frequency, types, potential clinical consequences and contributing factors of prescribing errors. Results Two hundred and fifty new prescriptions with 493 items were analyzed. There were 13 per 100 prescriptions with at least one prescribing error and 7.3% of the total items were prescribed incorrectly. The most common types of prescribing error were, an ambiguous prescription (61.1%) followed by an unrecommended dose regimen (13.9%). Logistic regression analysis showed that the risk of a prescribing error significantly increased when the prescription was written by a house officer (OR 4.72, p = 0.029). Errors were judged to be potentially non-significant (33.3%), significant (36.1%), or serious (30.6%). Conclusion The experience of prescribers is an important factor that contributes to prescribing errors in pediatrics. Many of the errors made were potentially serious and may impact on the patients' well-being.

Fulltext Acceptance of interprofessional learning between medical and pharmacy students in a prescribing skills training workshop: pre-post intervention study

Chua SS, Lai PSM, Sim SM, Tan CH, Foong CC

BMC Med Educ, 2019 Apr 05;19(1):101.
PMID: 30953493 DOI: 10.1186/s12909-019-1525-y

BACKGROUND: The success of interprofessional collaboration in healthcare services requires a paradigm shift in the training of future health profession practitioners. This study aimed to develop and validate an instrument to measure Student Acceptance of Interprofessional Learning (SAIL) in Malaysia, and to assess this attribute among medical and pharmacy students using a prescribing skills training workshop.
METHODS: The study consisted of two phases. In Phase 1, a 10-item instrument (SAIL-10) was developed and tested on a cohort of medical and pharmacy students who attended the workshop. In Phase 2, different cohorts of medical and pharmacy students completed SAIL-10 before and after participating in the workshop.
RESULTS: Factor analysis showed that SAIL-10 has two domains: "facilitators of interprofessional learning" and "acceptance to learning in groups". The overall SAIL-10 and the two domains have adequate internal consistency and stable reliability. The total score and scores for the two domains were significantly higher after students attended the prescribing skills workshop.
CONCLUSIONS: This study produced a valid and reliable instrument, SAIL-10 which was used to demonstrate that the prescribing skills workshop, where medical and pharmacy students were placed in an authentic context, was a promising activity to promote interprofessional learning among future healthcare professionals.

Antihistamines prescribed off-label among paediatric patients at a tertiary care hospital setting in Malaysia

Tan RW, Mohamed Shah N

Int J Clin Pharm, 2016 Oct;38(5):1277-85.
PMID: 27480982 DOI: 10.1007/s11096-016-0364-8

Background Antihistamines are widely prescribed to children but should be used with caution in young children. Objective To determine the paediatric prescribing pattern of antihistamines with a focus on the off-label prescribing and factors that influence such prescribing. Setting Paediatric wards of a tertiary care hospital setting in Malaysia. Methods The pharmacy-based computer system and medical records were used to collect the required data. Labelling status of each antihistamine was determined based on the information provided in the product leaflets. Main outcome measure Antihistamines prescribed off-label and factors associated with such prescribing. Results Of the 176 hospitalised children aged <18 years prescribed with an antihistamine in the year 2012, 60.8 % received it in an off-label manner. Of 292 antihistamine prescription items, 55.5 % were prescribed off-label. Loratadine (35.3 %) was the most frequently prescribed antihistamine and chlorpheniramine maleate (34.0 %) was the most common antihistamine prescribed off-label. The main reason for the off-label prescribing of antihistamines was prescribing at higher than the recommended dose (30.2 %). Binary logistic regression showed that children aged <2 years (OR 12.65; 95 % CI 2.87-55.67) and the number of medications received (OR 1.14; 95 % CI 1.00-1.29) were significant predictors for the off-label prescribing of antihistamines. Conclusion Prescribing antihistamines for children in an off-label manner was prevalent at the studied locations and warrants further investigation on the consequences of such prescribing.
